CEO Executive AssistantAntitrust law sits at the intersection of economics, regulatory strategy, and high-stakes litigation, making it one of the most operationally complex practice areas a law firm can build and sustain. For managing partners responsible for competition law practices, the operational demands are substantial: building and maintaining relationships with regulatory agencies across multiple jurisdictions, developing robust economics expert networks, managing the intense resource requirements of merger clearance work, and building the specialized talent pipelines that produce elite antitrust lawyers. Law firm managing partner business operations for antitrust practice require a distinctive combination of strategic vision, institutional relationship management, and rigorous operational execution.
Understanding the Antitrust Practice Landscape
Competition law practice encompasses several distinct service lines that each carry their own operational requirements and client development dynamics. Merger clearance work, which involves obtaining regulatory approval from agencies like the Department of Justice Antitrust Division, the Federal Trade Commission, and their international counterparts, generates significant fee volume and operates on deal-driven timelines that demand extreme responsiveness and resource flexibility. Cartel defense, representing clients under investigation for price-fixing, bid-rigging, and other coordinated conduct, requires deep relationships with criminal defense specialists and sophisticated internal investigation capabilities. Private antitrust litigation, involving class actions, direct purchaser suits, and competitor claims, generates sustained caseloads that can span years and require substantial litigation infrastructure.
Managing partners who attempt to build all three service lines simultaneously without adequate resources typically find that the most profitable segment, merger clearance, is underserved during active deal cycles while the more episodic segments, cartel defense and litigation, are over-resourced during quiet periods. Developing a clear resource allocation model that can flex with the deal cycle while maintaining baseline capabilities across all service lines is one of the central operational challenges of antitrust practice management.
The international dimension of competition law has become operationally unavoidable. Major transactions routinely require merger filings in 20 or more jurisdictions, and cartel investigations frequently span multiple continents. Managing partners who have not built genuine operational capabilities in EU competition law, Chinese antitrust review, and other major international regimes find themselves disadvantaged in competing for the largest and most sophisticated competition matters.
Regulatory Agency Relationships
No operational asset in antitrust practice is more valuable, or more carefully cultivated, than relationships with the senior staff of key regulatory agencies. The DOJ Antitrust Division and the FTC collectively employ hundreds of economists and attorneys whose decisions directly affect the outcome of every significant transaction and investigation in which your clients are involved. Managing partners who understand how these institutions operate, what factors drive their decisions, and how to communicate effectively with their professional staff consistently achieve better outcomes for clients than those who approach regulatory engagement primarily through formal submissions.
Building these relationships requires sustained investment over time. Active participation in bar association committees that engage with antitrust agencies, thoughtful submission of public comments on agency guidelines and policy developments, and professional development programs that maintain dialogue between agency staff and private practitioners all contribute to the institutional credibility that makes regulatory relationships genuinely valuable.
Former government service is one of the most reliable pathways to regulatory relationship capital. Managing partners who deliberately recruit former DOJ and FTC attorneys and economists into their practices, and who build lateral hiring programs that target senior government practitioners, gain both substantive expertise and institutional relationships that translate directly into client value. This requires a lateral hiring strategy that specifically targets government alumni at multiple career stages, from junior staff attorneys who will develop into senior practitioners over time to more senior officials whose relationships are immediately deployable.
Maintaining the trust of regulatory agency staff requires scrupulous professional conduct. Representations to agency staff that prove to be incomplete or misleading, even where they fall short of legal violations, damage relationships in ways that can take years to repair and that affect every client the firm represents before those agencies. The managing partner’s role in establishing and enforcing professional conduct standards for regulatory communications is both a compliance function and a long-term relationship management responsibility.

Economics Expert Networks
Modern antitrust practice is, at its core, an economics-intensive discipline. Merger review turns on market definition, competitive effects analysis, and entry barriers; cartel cases require economic analysis of pricing patterns and harm quantification; private antitrust litigation depends on expert economists for class certification, liability, and damages. Managing partners who have not built robust, reliable relationships with academic and consulting economists at both the pretrial and testifying expert levels are operating a structurally incomplete antitrust practice.
Building an economics expert network requires understanding the distinction between consulting economists, who can be engaged freely but cannot testify, and testifying experts, whose engagement must be carefully managed for work product and privilege purposes. Maintaining a diverse roster of economists across specializations, including industrial organization, labor economics, healthcare economics, and digital markets, allows the practice to match expert expertise to matter type without forcing clients into suboptimal expert relationships.
Academic economists affiliated with leading research universities bring credibility and methodological rigor that consulting economists, however experienced, sometimes cannot match. Developing relationships with academic economists through conference participation, co-authorship of articles and amicus briefs, and thoughtful engagement on the academic literature relevant to your clients’ industries requires sustained personal investment by senior antitrust practitioners.
Managing conflicts among expert economists is an operational function that deserves explicit attention. The pool of economists with the specific expertise and credibility to serve as testifying experts in major antitrust matters is not unlimited, and conflicts between matters, where the same economist has been engaged on positions that are adverse, can create complications that undermine your ability to field the best available expert team. Tracking expert engagements and conflict checking economists through the same rigor applied to attorney conflicts is an operational best practice that is more often honored in the breach than in the observance.
Merger Clearance Operations
Merger clearance is the highest-volume, fastest-moving segment of antitrust practice, and the operational requirements of major merger reviews are among the most demanding in any practice area. Second requests from the DOJ or FTC, which require production of vast volumes of documents and data in compressed timeframes, mobilize firm resources at a scale that requires careful advance planning even when the request itself cannot be anticipated.
Building a second request readiness infrastructure is an operational investment that managing partners in antitrust practices should prioritize. This includes maintaining relationships with e-discovery vendors who can scale rapidly to support large document productions, developing standardized second request response protocols that can be deployed immediately when a request arrives, and training sufficient attorney staff on the technical and procedural requirements of the process.
International merger filings require coordination across multiple jurisdictions with different filing thresholds, waiting periods, and substantive review standards. The operational complexity of managing a 25-jurisdiction filing program, with different deadlines, different information requirements, and different agency relationships in each jurisdiction, is substantial. Managing partners who have built either internal international capabilities or strong relationships with trusted local counsel in key jurisdictions can offer clients the seamless international coordination that major transactions require.
Fee and staffing planning for merger clearance work is complicated by the inherent unpredictability of regulatory outcomes. A transaction that is cleared without a second request generates a relatively modest fee; the same transaction subjected to an extended second request investigation can generate fees many times larger. This variability makes financial planning challenging but also creates significant upside in active deal markets.
Cartel Defense and Internal Investigations
Cartel defense work is among the most remunerationally significant and reputationally complex segments of antitrust practice. Managing partners who build cartel defense capabilities must navigate the tension between the substantial fees this work generates and the reputational considerations that attend representing clients in criminal price-fixing or bid-rigging investigations.
Building genuine criminal defense capabilities within a civil antitrust practice requires developing strong working relationships with white-collar criminal defense practitioners, either within the firm or through established co-counsel arrangements. The procedural, evidentiary, and ethical dimensions of criminal antitrust work differ significantly from civil practice, and attempting to handle criminal exposure without appropriate criminal defense expertise creates risk for both the client and the firm.
Internal investigation capabilities are closely related. When clients learn that they may have antitrust exposure, either through a government inquiry, a whistleblower report, or a civil suit that suggests coordinated conduct, the first operational response is typically an internal investigation to assess the nature and extent of the conduct. Managing partners who have built the forensic, interviewing, and privilege management capabilities to conduct rigorous internal investigations, and who can produce results that will withstand subsequent regulatory scrutiny, provide a service that is both genuinely valuable and operationally distinctive.
Building Antitrust Talent Pipelines
The supply of elite antitrust lawyers is constrained by the difficulty of the work and the length of the development timeline. Senior antitrust practitioners capable of leading major merger reviews or complex cartel defenses have typically spent 15 or more years developing the substantive expertise, regulatory relationships, and business development capability that make them practice leaders. Managing partners who understand this development timeline build talent pipelines that extend forward 10 years, not just into the next hiring cycle.
Law school recruiting for antitrust should target candidates with economics backgrounds or demonstrated quantitative aptitude. The most effective antitrust lawyers can read an economic model, evaluate empirical evidence, and communicate with expert economists as genuine intellectual peers. Law graduates with only legal training are at a persistent disadvantage relative to those who can engage substantively with the economic core of competition analysis.
Structured training programs that provide junior associates with substantive exposure to all segments of antitrust practice, merger review, cartel defense, civil litigation, and regulatory counseling, while deepening technical expertise through working relationships with testifying economists and regulatory agency alumni, produce more versatile and more valuable senior practitioners than programs that specialize associates too early.
According to research published in the Harvard Business Review, professional service firms that invest in structured associate development programs retain high-performing talent at rates significantly above industry averages, a finding that is particularly relevant in antitrust practice where the cost of losing a senior practitioner who takes institutional relationships and client relationships with them can be severe.
Financial Management of Antitrust Practice
Antitrust practice generates substantial revenue per matter but also carries substantial costs. Expert witness fees, e-discovery costs, international counsel fees, and the resource-intensive nature of merger review and cartel defense all consume significant portions of matter economics. Managing partners who track matter profitability at the practice area level, and who develop cost management protocols for high-volume cost categories, maintain the economic discipline that keeps antitrust practice financially attractive relative to its resource demands.
Billing model innovation is increasingly relevant in antitrust. Some sophisticated clients, particularly those with in-house antitrust teams, are pushing for alternative fee arrangements that share risk with outside counsel or provide budget certainty for discrete phases of work. Managing partners who can offer credible alternative fee arrangements for defined work phases, like second request responses or first-round international filings, capture clients who would otherwise prefer competitors willing to share economic risk.

Building a Reputation in Competition Law
Managing partners in antitrust practice understand that reputation is built in court, before agencies, and in the academic and professional literature. Publishing thoughtful analysis of significant regulatory decisions, participating as speakers at academic and practitioner conferences, and maintaining visible engagement with the academic economics community all contribute to the reputational capital that attracts sophisticated clients and elite lateral candidates.
Thought leadership in antitrust is not marketing in the traditional sense. Agency staff, in-house counsel, and academic economists all read the literature and attend the conferences where substantive competition law ideas are debated. A managing partner whose practice contributes meaningfully to those conversations builds the kind of credibility that generates client inquiries and referrals that no amount of traditional legal marketing can replicate.
The managing partner’s personal visibility in antitrust matters, appearing as lead counsel in significant agency proceedings or high-profile litigation, remains the most powerful single driver of practice reputation. Ensuring that the managing partner maintains an active client-facing practice, rather than retreating entirely into administrative responsibilities, is both a business development imperative and a quality signal to the talent that the practice needs to attract and retain.
